Reincarnation: the Main Counterattack of the Sadistic Female Heroine

Traveling through a book and becoming a heroine is supposed to cover the sky with one hand, but this is a sadistic novel! The original heroine had a miserable life experience, resigned and fell in love with the ruthless male protagonist who was cruel to her... Wait, this is not the script she should get! Scumbag male protagonist? Evil heroine? Haha, she wrote the plot, so can she still be unable to defeat these paper people? However, Jiang Xiaxia, who thought she was in control of the situation, soon discovered that things were not simple: a best friend who was supposed to die, a character that never existed, and a branch line hidden in a corner... And—— The innocent second male lead is actually a wolf in sheep's clothing.
